Bulls' Portis out 2-4 weeks with ankle injury

It's back to the injury ward for Bobby Portis.

The Chicago Bulls' big man is expected to miss two-to-four weeks with a right ankle injury, the team announced Thursday. Portis hurt himself in Chicago's loss to the Brooklyn Nets on Wednesday.

Portis had only played five games since returning from a six-week layoff due to a right knee injury. In nine total contests this season, he's averaging 12 points and eight rebounds.

The injury could mean the return of Jabari Parker to the Bulls' rotation. Parker has recorded a DNP in the last three games.
